This data collection contains data gathered in a
longitudinal study of a sample of men aged 65 to 92 who were in good
health during the first wave of the study in 1957. The chief aim of
the study was to focus on the nature of the normal aging process in
individuals of advanced age. The 47 study participants had not
suffered from accidents, illnesses, severe emotional or personality
problems, or environmental difficulties that might have led to
premature aging, but 20 participants showed evidence of asymptomatic
subclinical disease. This group represented the typical or "average"
healthy aged individual with minimal degrees of physical
pathology. Five years later, in 1962, a follow-up study was conducted
with 29 of the 39 men still alive. The second follow-up, done in 1968,
involved 19 of the surviving 23 men. The data are arranged in files by
year: 1957, 1962, and 1968. Included are psychiatric data and medical
evaluative data as well as various psychological and medical test
scores (e.g., psychometric data, electroencephalographic data,
audiological test data, responses to the Minnesota Multiphasic
Personality Inventory (MMPI), Rorschach test results, personality test
results, Inflund Selective Recall Test results, audiometric conduction
findings, clinical psychology ratings, cerebral blood flow, and
metabolism studies), and biographical and demographic data.
